2 ID problems, 1thread

[Killingtime]

The first ID I'm requesting is for a wispy looking clear cyano-looking growth on the underside of my rock

The next issue I have is what I believe are a type of hydroid...maybe???

Any help on IDing these things that you reef gurus can give me would be much appreciated
Any recommendations for removal would be immeasurable

This is the one I'm thinking is a type of hydroid ???

This is the one that has me more concerned. It appears as a wispy clear/white substance. And it is growing in a shaded area. So I'm guessing its not photosynthetic.

If you need any more pics, I'll be more than happy to oblige.

So, I think I have the hydroid figured out, Obelia dichotoma. I still need help on how to get rid of it, but at least I know what it is.

I'm still looking for help with the clear wispy stuff if anyone has any ideas it would be appreciated.
